Answer:
[2, 15]
Step-by-step explanation:
The graph shows the n/4 algorithm to be better (smaller run time) for n in the range 2 to 15.
First we simplify the inequality
1. <em>multiply 6 by the other side of the inequality (-4) </em>
Now we have ...
a > -24
Anything that can be a solution to the inequality <u>must be greater than -24</u>
-18 is greater than -24
This means that, YES! a = -18 IS a solution to the inequality
Answer:
28.26
Step-by-step explanation:
The area of a circle is πr^2. So all you would do you be π times 3 to the power of 2 to get abour 28.26.
Answer:
135 to nearest whole number.
Step-by-step explanation:
∑ 5(4/3)^(k-1) from k = 1 to k = 8.
First term = 5 , second term = 5*4/3
This is a Geometric series with first term a1 = 5 and common ratio r = 4/3.
The sum of n terms = a1(r^n - 1) / (r - 1).
The sum of 8 terms is given by 5 * (4/3)^8 - 1) / ( 4/3 - 1)
= 135 to the nearest whole number.
